Take a look at the equipment police use

This is the stinger. When police need to stop a driver themselves they may spread out these row of spikes to punch holes in their tyres. Very specialist equipment only trained officers can use.

What is today's operation all about?

The operation is all about the interceptor team, who go out to targeted areas and try to prevent crime from happening in the first place.

Rather than responding to 999 calls, the interceptor team go to wherever police are seeing trends or spikes in crime.

For example, Hounslow Town Centre is seeing an increase on knife crime and there has been gang avtivity in Chiswick. These officers look out for suspicious people or cars and try to catch criminals before any harm is done.
